Let's just win out and stay off that 4/5 line all together.
I don't know about anybody else, but I have nightmares about being a 4/5. At best, it has left great Illini teams losing in the Sweet Sixteen to #1 seeds that we just could not hang with ... at worst, it has been a quick end to an otherwise good season:
Modern NCAAT Format: Illinois as #4 or #5 Seed
1986: #4 seed. Lost in Second Round to #5 Alabama 58-56.
1990: #5 seed. Lost in First Round to #12 Dayton 88-86.
1998: #5 seed. Lost in Second Round to #4 Maryland 67-61.
2000: #4 seed. Lost in Second Round to #5 Florida 93-76.
2002: #4 seed. Lost in Sweet Sixteen to #1 Kansas 73-69.
2003: #4 seed. Lost in Second Round to #5 Notre Dame 68-60.
2004: #5 seed. Lost in Sweet Sixteen to #1 Duke 72-62.
2006: #4 seed. Lost in Second Round to #5 Washington 67-64.
2009: #5 seed. Lost in First Round to #12 Western Kentucky 76-72.
2002: #4 seed. Lost in Second Round to #5 Houston 68-53.
When you are on that 4/5 line, you are signing yourself up for a brutal battle in the Second Round with an equally matched team (or a potential First Round scare like in 2003 or 2022 even if you win). Then if you survive that fight to the finish, you likely have a #1 seed waiting for you.
I know the grass is not always greener, but as an Illini fan who has watched us lose earlier than I felt we should SO many times in the top half of the bracket, being a #3 seed just sounds so nice, haha.
